ABSTRACT

ABSTRACT Objective: This study aimed to present a temporal and spatial analysis of the 2018 measles outbreak in Brazil, particularly in the metropolitan city of Manaus in the Amazon region, and further introduce a new tool for spatial analysis. Methods: We analyzed the geographical data of the residences of over 7,000 individuals with measles in Manaus during 2018 and 2019. Spatial and temporal analyses were conducted to characterize various aspects of the outbreak, including the onset and prevalence of symptoms, demographics, and vaccination status. A visualization tool was also constructed to display the geographical and temporal distribution of the reported measles cases. Results: Approximately 95% of the included participants had not received vaccination within the past decade. Heterogeneity was observed across all facets of the outbreak, including variations in the incubation period and symptom presentation. Age distribution exhibited two peaks, occurring at one year and 18 years of age, and the potential implications of this distribution on predictive analysis were discussed. Additionally, spatial analysis revealed that areas with the highest case densities tended to have the lowest standard of living. Conclusion: Understanding the spatial and temporal spread of measles outbreaks provides insights for decision-making regarding measures to mitigate future epidemics.

ABSTRACT

OBJETIVOS: 1- Padronizar a genotipagem em larga escala para determinação de antígenos eritrocitários e plaquetários pela plataforma de OpenArray®em doadores de sangue. 2- Elaboração de software para registro destes doadores, com interface com o equipamento de genotipagem. METODOLOGIA: Extração automatizada de DNA e genotipagem através demicroarranjos líquidos (OpenArray®) para 32 alelos codificantes de antígenos eritrocitários e plaquetários. RESULTADOS: Foi realizada a genotipagem de 5487 doadores para os antígenos propostos, de forma completamente interfaceada e automatizada. O ensaio customizado de Open Array® mostrou-se acurado e de rápida execução. Elaborou-se software próprio para interfaceamento dos resultados da genotipagem e busca dos genótipos. CONCLUSÃO: Padronizou-se estratégia efetiva para rastreamento de doadores de sangue com fenótipos raros. A automação de todas as etapas experimentais e o interfaceamento completo dos dados minimizaram os erros humanos e aumentaram a rapidez do processo descrito, que pode ser aplicado como estratégia de genotipagem de doadores de todo o Estado de São Paulo.
